HOT-WATER HEATER.

I Specification of Letters Patent.

Patented Feb. 11,1908.

Application filed September 13; 1906. Serial No. 334.387.

.To all whom it may concern:

Be it known that we, EDWIN S. DECKER, a subject of the Kingof Great Britain, and resident of Malden, county of Middlesex, State of Massachusetts, and GEORGE H. GIBBY, a citizen of the United States, and resident of Boston, county of Sullolk, State of Massachusetts, have invented an lmprovement in HotWater Heaters, of which the followingI description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of a hot-water heater constructed. or built up of a plurality of detachably connected water sections and an independent casing comprising separable circular members superposed one upon the other, and. independent ofthe water sections, so constructed and arranged as to be easily and cheaply Inolded andV cast, and capable of indefinite enlargement to suit circumstances.

We `have so constructed the various parts of the heater that the heating medium is caused to completely encircle or surround the water sections, thereby `providing' for the maximum heating effect, While at the same time permitting the water sections, one or more, to be removed without disturbing the casing other than removing the top or cover thereof.

The various novel features of our invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a vertical diametral section of a hot-water heater embodying one form of our invention, Fig. 2 is a transverse section thereof on the line 2 2, Fig. 1 looking down; Fig. 3-is a side elevation of one of the Water sections.

Referring to the drawings, the metallic base 1 having a suitable door 2, constitutes the ash-pit 3, a grate 4 being supported by the base, which latter also sustains the fireepot 5, shown as double-walled to form a water-jacket or receptacle 6 around the fire, the waterjacket having an upturned outlet 7 terminating in a threaded hub 8 at the center of the iire-pot.

In the present embodiment of our invention We provide a plurality of circular watersections 9, made as castings, the upper and lower sides preferably sloping or converging from the center to the periphery. Each water-section, except the top-most one, is providedwith opposite central hubs 10, 11 on its upper and lower sides, respectively, and internally threaded, as shown. An externally threaded coupling, shown as a short tube or sleeve 12, is screwed into the upper hub of one section and the lower hub of the section next above is then screwed onto the coupling, so that the sections are detachably and centrally connected or coupled together.

The lowermost water-section is coupled in like manner to the hub 8, as shown in Fig. 1. Upright webs 13, shown in Fig. 2 as curved or S-shaped, are cast in each section and serve to strengthen it and also to assist in effecting circulation of the water through the section, the water entering at the bottom of each section and leaving it at the top. lf the sections are relatively small they can be screwed together by hand, but this is sometimes difficult in the case of large and heavy sections, and to facilitate assembling or separation we provide the sections with external recesses or pockets 14 at the periphery, to be engaged by a suitable tool in the nature of a spanner, whereby rotation of the section is greatly facilitated. Herein we have shown the uppermost section 9X as provided with an upper threaded hub 1() o'lfset from the center, to receive the outlet pipe 15, but in other respects it is like the other section.

The casing is composed of a plurality of cylindrical members 16, ieach one having an annular uptur'ned lip or flange 17 at its upper edge, to receive the bottom of the member next above it, and the several members are provided with clean-out openings normally closed by suitable doors, as 18. The bottom member, which rests upon the fire-pot 5, within the flange 5 thereof, does not require such a clean-out .opening as the bottom of the lowest water section is accessible through the fire-pot.

In order to cause the heating medium to circulate around the water-sections we provide the casing members Lwith segmental lateral partitions or flue plates, which extend inward from said members close to the perF imeters of adjacent water sections, the partitions being arranged in alternation. Herein we have shown substantially semi-circular partitions 19, extending inward from the casing members adjacent the upper edge thereof, the partition onv one member being on the side of the heater opposite the partitions of the members next above and below it. In Fig. 2 the partition or flue plate 19 of the topmost casing member 16 is shown in plan, and rom Fig. 1 it will be seen that each partition closely approaches the periphery of the adjacent water-section. Such alternate arrangement of the partitions causes the products of combustion to follow the course indicated by the arrows Fig. 1, kso that the entire external surface of each water-section is exposed to the heat while a thorough circulation of the heating medium is attained. A suitable cap or cover 2O completes the casing, it having an outlet hub 21 and a hub 22 through which the water outlet 15 passes, and preferably the cap is provided with a clean-out opening and closure 23.

It will be seen that the water-sections can be easily cleaned or scraped when necessary through the various clean-out openings of the casing without any disturbance of the structure. Furthermore, as the water-sections are absolutely independent of the casing the latter can be set up after the water-sections are set up, so that the latter can be tested for leakage before any of the casing is provided, the casing members being set or built one upon the other and made tight by suitable cement.

If it is necessary to remove one or two water-sections, either separately or together, for any reason after the heater is set up, this can be done by removing the cap or cover 2() and unscrewing the necessary upper watersections down to the one necessary to repair Without taking down the casing, and. when repairs have been made the sections can be replaced in a similar manner. So, too, the casing can be removed without distributing the sections, if it is necessary to repair or tighten any one ol the sections.

The heater can be made of any desired capacity simply by increasing the number of water-sections and casing members, so that the heater is capable of indeiinite enlargement.

The various parts can be easily and cheaply molded and cast, requiring very little finishing or machining, thereby greatly reducing the cost of production.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a water heater, a plurality of detachably connected water sections, a casing comprising separable cylindrical members adapted to be superposed one upon the other around and wholly independent of the water sections, and segmental lateral partitions or flue plates carried byfand extended inward from the casing members close to the perimeters of adjacent water sections, said segmental partitions being arranged in alternation. V

2. In a water heater, a plurality of centrally and detachably connected like, circular water sections, an independent inclosing casing comprising a series of separable cylindrical members adapted to be superposed one upon the other around and independent of the water sections, the height of a member being equal to the distance between the tops of two adjacent water sections, said members having clean-out openings opposite the spaces between the water sections, and segmental, lateral partitions or flue plates carried by and extended inward from the casing members close to the peripheries of adjacent water sections, said segmental partitions being staggered to cause the heat to pass in a tortuous path about the Water sections.

3. In a water heater, a series of like, circular water sections each having a central threaded hub on its upper and lower side, and a threaded coupling member to engage the opposed hubs of and connect two adjacent sections, each section having a series of peripheral pockets or recesses to cooperate with a tool and facilitate rotative movement of the section when connecting it with or disconnecting it from another section, and a series of superposed cylindrical members forming an linclosing casing around and wholly independent of the water sections, leaving free spaces between the peripheries of the latter and the inclosing casing to permit the engagement of a tool with the peripheral pockets in the water sections.

In testimony whereof, we have signed our names to this speciicatiomin the presence of two subscribing witnesses.
